Letters Patent No. 93,428, dated August IO, 1869.

IMPROVEMENT IN SPURS FOR EXCELSIOR-MACHINES.

The Sucheule referred to in these Letters Patent and lmaking part of the same.

Be it known that I, JncoB AUGUSTUS FoLsoM, of South Bend, in the county of St. Joseph, and State of Indiana, have invented a new and useful Improvement in Spurs for ExcelsioreMachines; and I do declare that the following isa true and accurate description thereof, reference heinghad to the accompanying-drawings,-

and to the letters' of reference marked thereon, and being a part of this specification. Y v Figure 1 is a perspective view of my' invention. Figure 2 is a vertical section of the same. Like letters referto like parts in each ngure.` The nature of this invention relates to an' improvement in the construction and operation of vcuttingspurs to be used in excelsior-lnachines,.in place of the spurs in common use; and consists in airanging a series of circular cutters upon a properY arbor, which is soconstructed as to rotate-upon suitable journals, or to be held rigidly in position by means of square shoulders upon the arbor, so that the spurs maybe used as rotary or stationary cutters, as may be desired.

A, in the drawings, represents an arbor, providedY at its ends with journals, B.

Upon this arbor is' loosely sleeved a vseries ofcircular knives, G.

A rigid shoulder, D, on the arbor is prorided, against' which the cutters are placed. j

Betweenthe journal, on the opposite end ofthe arbor, and the cutters, a thread iscut upon the arbor, and a jam-nut, E, engages with said thread, by means of which the' knives are held firmly in place on said arbor, and prevented from rotating-on said arbor by tightening said nut.

Placing the journals` into suitable bearings on any eXcelsior-machine, the arbor will rotate and with it the lcutters will also revolve.

By ,placing the shoulder and nut in other bearings,

-the arbor-fand knives Will-remain stationary, While the timber being cnt will pass under them.

When used as last described 'and become dulled, the arbor may be lifted out of the jaws or bearings, and turned one-quarterway round and dropped to place, when sharp edges will be again presented.

Should it be desired to increase the distances between the cutters, small disks oi' collars may be inserted on the arbor between the knives.

The knives when used as stationary cutters, may he I round, oval, square, or triangular, as maybe most convenient and desirable.

I do not claim to have made any alteration in the construction of' the' machines in use for cutting excelsior, which is used for filling mattresses, cushions, &c., l

FOLSOM.
